!Page.IsPostBack

[Guest]

I have dropdown list in Login page. The data is adding twice because the
Page_Load event is executing twice. But I am checking !Page.IsPostBack
property. First time the value for '!Page.IsPostBack' is 'true'. When it goes
for second time it is not setting to 'false'. Please remember the '!' before
the property. Which is means that still it is not recognizing that the page
is loaded.

Basically the Login page is redirecting from the Authenticate page.

Any help please, thanks in advance.

Basically the Login page is redirecting from the Authenticate page.

Redirection is not the same as a post back. The HTML form in the page
must be submitted to the server using HTTP POST to cause a postback.
Redirection just results in a HTTP GET, hence IsPostBack is false.
